The Shifting Landscape Of Adolescent Wellness In Boarding Schools: Can Time Spent Off Screens And Outdoors Improve Adolescent Wellbeing?, Kristen H. Peterson

Dartmouth College Master’s Theses

For nearly twenty years I have worked directly with adolescents as an independent school educator. Whether in the classroom, on the field, or in the dorm, I have observed and supported students through their middle and high school experiences. During this time, I have witnessed an alarming shift in adolescent physical, emotional, and social wellbeing. Concurrently, I have observed a dramatic increase in the amount of time students spend using screen-based devices, and a decrease in their time spent outdoors.

Using research to ground my anecdotal accounts in empirical understanding, my thesis examines whether or not screen use might help …

Discord In Concordance Cosmology And Anomalously Massive Early Galaxies, Stacy S. Mcgaugh

Faculty Scholarship

Cosmological parameters are constrained by a wide variety of observations. We examine the concordance diagram for modern measurements of the Hubble constant, the shape parameter from the large-scale structure, the cluster baryon fraction, and the age of the universe, all from non-CMB data. There is good agreement for (Formula presented.) and (Formula presented.). This concordance value is indistinguishable from the WMAP3 cosmology but is not consistent with that of Planck: there is a tension in (Formula presented.) as well as (Formula presented.). These tensions have emerged as progressively higher multipoles have been incorporated into CMB fits. This temporal evolution is …

Designing Clinical Trials For Patients Who Are Not Average, Thomas E Yankeelov, David A Hormuth, Ernesto A B F Lima, Guillermo Lorenzo, Chengyue Wu, Lois C Okereke, Gaiane M Rauch, Aradhana M Venkatesan, Caroline Chung

Faculty, Staff and Student Publications

The heterogeneity inherent in cancer means that even a successful clinical trial merely results in a therapeutic regimen that achieves, on average, a positive result only in a subset of patients. The only way to optimize an intervention for an individual patient is to reframe their treatment as their own, personalized trial. Toward this goal, we formulate a computational framework for performing personalized trials that rely on four mathematical techniques. First, mathematical models that can be calibrated with patient-specific data to make accurate predictions of response. Second, digital twins built on these models capable of simulating the effects of interventions. …

Bond Slip Characteristics Of Hb⁃Frp Based On Arc⁃Length Method, Xu Xiangfeng, Li Pengfei, Li Xinxin, Zhang Luke, Gao Lei

Journal of China & Foreign Highway

The bonding performance between hybrid bonding FRP (HB-FRP) and concrete is crucial for HB-FRP reinforcement of concrete structures. This paper built a simple shear numerical model for HB-FRP, which considered both the interfacial bond slip between FRP and concrete by adopting bilinear constitutive analysis, and the interfacial bond slip at the steel fastener location by employing trilinear constitutive analysis. Meanwhile, the bond slip properties at the steel fastener location were simulated by double springs. Based on the arc-length method, the entire process of loading and unloading of the HB-FRP simple shear model was carried out to study its stress performance. …

Electric Fields In The Atmosphere Might Help Snow Crystals Form, Joseph Cooney

Research on Capitol Hill

Orographic clouds generally form over mountains when valleys are sunny. The unstable atmosphere can trigger clouds over the mountains, which can be convective. When this happens, the cloud particles (water droplets and ice particles) become charged, ultimately creating ice crystals. I wanted to evaluate the impact of electricity on the formation of ice crystals and built a computer simulation to do so.
